Embodiment 1

[0036] According to an embodiment of the present application, an embodiment of a network traffic control system is provided, which can be applied to network security protection between an internal network and an external network, between a private network and a public network, and between a computer and a network connected to it.

[0037]Due to the openness of the Internet, while the Internet brings convenience to people's life and work, people pay more and more attention to information security. As an isolation technology, a firewall can isolate any network between two networks (including but not limited to two internal networks, internal network and external network), or terminal devices (including but not limited to mobile phones, laptops, computers, tablets, etc.) A device that can be connected to the Internet) and the network communication traffic between the network are inspected, filtered and restricted to prevent unauthorized access, thereby ensuring the security of the...

Embodiment 2

[0067] According to the embodiment of the present application, an embodiment of a network traffic control method is also provided. This embodiment can be applied to the network traffic control system in Embodiment 1, including but not limited to the scenario in Embodiment 1. It should be noted that the steps shown in the flowcharts of the accompanying drawings may be performed in a computer system, such as a set of computer-executable instructions, and that although a logical order is shown in the flowcharts, in some cases, The steps shown or described may be performed in an order different than here.

[0068] Because the existing technology uses multiple firewalls connected in parallel to form a firewall cluster to realize the function of a traditional single firewall, although the problem that network services or applications are affected by the firewall bandwidth due to the access of a single firewall can be overcome, due to the scattered flow of network traffic With multip...

Embodiment 3

[0122] According to an embodiment of the present application, an embodiment of a device for implementing the above network traffic control method is also provided, Figure 13 is a schematic diagram of a network traffic control device according to an embodiment of the present application, such as Figure 13 As shown, the device includes: a receiving unit 131 , an analyzing unit 133 and a first determining unit 135 .

[0123] Wherein, the receiving unit 131 is configured to receive flow feature information reported by the firewall;

[0124] An analyzing unit 133, configured to analyze flow characteristic information and / or network behavior information determined by the flow characteristic information, and obtain an analysis result;

[0125] The first determining unit 135 is configured to determine a control instruction to be delivered to the firewall according to the analysis result, wherein the control instruction is used to control network traffic flowing through the firewall...

Abstract

The invention discloses a network flow control method, a network flow control system and a safety protection device. The method comprises the following steps: receiving flow characteristic informationreported by a firewall; analyzing the flow characteristic information and / or the network behavior information determined by the flow characteristic information to obtain an analysis result; and determining a control instruction issued to the firewall according to the analysis result, the control instruction being used for controlling network traffic flowing through the firewall. The technical problem that an existing firewall mode is poor in network flow protection effect is solved.

Description

technical field [0001] The present application relates to the field of computer networks, in particular, to a network flow control method, system and safety protection device. Background technique [0002] A firewall is a technical measure to protect computer network security. It isolates the internal network from the external network by establishing a corresponding network communication monitoring system on the network boundary to block network intrusion from the outside. figure 1 It is a schematic diagram of an optional firewall protection architecture according to the prior art, such as figure 1 As shown, when the traffic of the operator on the side of the Internet Service Provider (Internet Service Provider, ISP) enters the router, the traffic is distributed inside the firewall cluster through the load balancing policy of the router. After the firewall checks and filters the traffic flowing through its own node, it forwards the traffic to the switch and forwards it to t...
